UNITED STATES PATENT OFFICE.

EDWARD LESLIE, OF ORANGEVILLE, ONTARIO, CANADA, ASSIGNOR TO THE ROTARY STEAM SNOW SHOVEL MANUFACTURING COMPANY, OF PAT- SNOW- PLOW.

SPECIIICATION forming part of Letters Patent No. 338,759, dated March 30,1886.

Application filed August 17, 1885. Serial No. 174,547.

T all whom it may concern:

Be it known that I, EDWARD LESLIE, of the town of Orangeville, in the county of Dufferin, in the Province of Ontario, Canada, gentleman, have invented certain new and useful Improvements in Snow-Flows, of which the following is a specification.

The invention relates to that class of snowplows in which a series of shovels are caused to to revolve within a casing having an aperture in it, through which the snow is discharged by centrifugal force produced by the revolving of the shovel within the casing, and the object of the present invention is to arrange on the same shaft as the shovels a series of shears arranged to gather the snow into the shovels as the whole revolve; and it consists, essentially, in locating a plate between each pair of shovels designed to form a series of shears to shear off the face of the snow-bank being attacked, and gather the snow thus cut off into the space between the shovels, substantially as hereinafter more particularly explained.

Figure 1 is a sectional elevation of my improved snow-plow. Fig. 2 is a perspective detail of my improved wheel, formed by the shears and shovels. Fig. 3 is an enlarged detail of a section of the wheel. Fig. 4. is a detail of spider. Fig. 5 is a detail of the shear- 0 ing-plate.

A is the driving-shaft, preferably carried in a long bearing, B, which is supported on the truck C in any suitable manner. The shaft A derives motion from any suitable motor,

3 5 either carried on the truck C or otherwise located.

In the drawings I show a beveled pinion, D, secured to the shaft A and meshing with the beveled pinions E, located on either side 0 of the bearing B, suitably journaled and having their shafts arranged to connect with a motor.

E is a casing, made substantially in the manner described in United States Patents Nos.

4 5 297,408 and 317,809, patented to me.

F is a disk secured to the driving-shaft A, and designed to fit against the back of the casing E. From this disk F a series of shovels, G, extend at right angles to the face of the said disk.

(No model.)

H is what may be termed a spider, shaped substantially as shown in Fig. 4, and secured to the end of the shaft A, so as to form a support for the shovels G. It will be noticed that the spider II is composed of a series of 5'; arms, a, radiating from a hub, I), secured to the shaft A. These arms a form supports for the outer edges of the shovel G, and are braced together by the inner and outer rings, (Z and e. The spaces bounded by these rings d and eand by each pair of arms a are covered by the plates I, which are preferably bent at an angle, as shown in Fig. 5, and are preferably hinged at their center to the rings (1 and 6, so that one-half of each space may be covered by one-half of each plate I, while the other half of each plate extends outwardly at an angle, as indicated, so as to form a series of shears extending from the face of the rings 01 and 6, designed to shear off from the face of the bank of snow and gather into the spaces between the shovels the snow which is discharged from the casing A by the revolving of the said shaft.

Asstated, Ipreferabl y-hinge theplates I, which 7 5 I do for the purposeof reversing the direction in which the shovels revolvethat is to say, when it is desired to discharge the snow from one side of the shovels, the said shovels are caused to revolve in the direction indicated by arrow in Fig. 2, and the plates I are in this case set as shown in that figure. If it is desired to discharge on the opposite side, the shovels are caused to revolve in the opposite direction, and the plates I are set so as to open 8 5 the opposite side of the space.

A series of spring-catches, f, are formed on the ring (I, so as to hold down whichever side of the plate it may be desired to retain.

Although I prefer the plate I to be shaped and hinged as indicated, a portion of the object of my invention would be obtained by making the plate a permanent fixture; but in such a case the shovels could only be used for discharging on one side of the machine.

\Vhen the plates I are hinged, it will be un derstood by reference to the drawings that they are self-setting-that is to say,whichever way the shovels are caused to revolve the plates I open, so as to act as shears in whichever way the wheel revolves, it being intended center between the shovels G, substantially as and for the purpose specified.

3. A-seriesof shovels, G, connectedrto and 15 radiating from the shaft A, theringsd and e, designed to brace the shovels together, as speci-. tied, in combination with the bent plates 1, hinged to the rings d and e, substantially at the center of vtheplates and betweenthe shovels 2o 7 4. I The bent plates I, hinged to'the rings d and 'e, in combination with thespring-catches F, arranged substantially as and for the purpose specified.
